Abstract

Systems and methods are provided for determining a channel quality indicator (CQI) for receivers that exhibit non-deterministic behavior during the CQI selection process. A codeword is received over a transmission system at a receiver, and a performance measure that is dependent on the CQI is determined for the codeword. The receiver determines an objective function that is based on the CQI and the performance measure, and selects a value for the CQI by performing an optimization technique on the objective function. The optimization technique is performed on the objective function over a range of candidate CQI values, and the selected value for the CQI is the candidate CQI value that optimizes the objective function.
